Rodenstock 360mm - f6.8 APO Sironar S lens (Copal 3)

The Apo-Sironar-S is a lense for universal use which has been modified to provide the highest image reproduction quality. Its special stregths can be seen when complex, fine structures in the adjustment range have to be reproduced.

Its field angle has been increased to 75 degrees and so permit even more generous shifts. Therefore is the Apo-Sironar-S also the ideal standard lens for applications which require particulary large parallel shifts to correct the perspective.

As a result of elimination of the secondary spectrum thanks to the use of ED glass materials with anomalous dispersion, no visible colour fringing occurs even at edges with extreme contrast. In addition, the light fall-off towards the edge has been reduced for a more uniform illumination.
